Alias parts PHP script

[Allen Smith]

The type meta can be a pain to parse indeed.

This is what I'm using at the moment:

Code:

meta: "LDRAW", "LDRAWORG", "LDRAW_ORG", "!LDRAW_ORG", "OFFICIAL", "UNOFFICIAL", "UN-OFFICIAL",

type:   "Part",  "Subpart",  "Primitive",  "48_Primitive",  "Shortcut",  "File",  "Model",  "Submodel",  "Element",  "Sub-part",  "Hi-Res primitive",  "Alias",  "Cross-reference",  "Configuration",  "Unofficial_Primitive",  "Unofficial_Part",  "Unofficial_Model"

qualifier: "Physical_Colour", "Alias"

All case insensitive, and do note the space in "Hi-Res primitive" you need to keep an eye on that while parsing.

You also need to skip an optional "LCAD" after the main meta keyword.

Bleah.

Let us assume I presently have no need or interest to fully parse this creature. I only want to know if a part in the latest official library is an alias or not. Is looking for

Code:

!LDRAW_ORG Part Alias

sufficient, or do I need to consider other permutations of this meta's apparently-tortured history?

Next problem: the official spec is missing a number of the things Roland is parsing for, including any discussion of (qualifiers), which is what precipitated this question in the first place. I would like the spec to match the library and the library to match the spec. In a perfect world, that would mean adding new stuff to the spec, removing old cruft, and adjusting the library files to match.
